  1. Dont be afraid to sand the heck out of it.   You can sand all of that off and restain it.   The planks are thick enough.   Try t again but make sure you use a mixture of more natural stain vs golden oak.  I would start with something like a 20 % stain mixture to 80% natural.   See what happens.    You can remove that stained layer if you just sand it off.   Then sand it with a very fine 400 - 600 wet dry paper.   Then apply the stain mixture.

    You can use the plans and use CNC to cut out the parts.   As long as they are for your own personal use on this project then feel free to use any method to cut out the parts.  As the hobby matures,  folks are starting to use new tools and technology.   Who are we to stand in the way.  I happen to prefer a sharp chisel or a scroll saw but other now find CAD and CNC or even laser cutting just as much a part of the process.   Its no different than someone using a Sherline Mill or Lathe vs.  a jewelers saw and chisel.   

     

    The project is an introduction to scratch building and scratch building techniques.  CNC is just one of those techniques that are newer.  CAD and CNC are fast becoming a fun part of this hobby for lots of people.  They should be made to  feel welcome here.  So again I will welcome you to the group and forum.

     

    Build away and enjoy the project.

     

    The only disclaimer is that it be for your own personal use and you cant distribute cut parts to other builders.   I will enjoy watching you progress and dont hesitate to ask me any questions.  You have the complete blessing and authority from ADMIN and Owner alike.

  3. Jerry...you asked

     

    Once you have made three left-hand ropes, you then twist these to achieve the right-hand cable.  Do you have to tension the laid-up left-hand rope in the opposite direction before you twist them into the right-hand cable? 

     

    The answer is yes...Twist them even more to create a tight twist that will want to untwist when you are done.  This "wanting to untwist"  creates the tension when you wind all three in opposite direction afterwards.   Its the same as when you started with the smaller ropes....You must twist the individual strands first...otherwise they have no tension.....which will soon be equalized when you twist all three together in the opposite direction.  You see,  when folks just place 9 strands on a rope walk (3 on each without having turned them into rope first) and just do the initial twist of the nine.....there was no tension to keep those initial twisted three threads together as rope.    In fact,  if this is what you have tried as Michael has.....try this experiment.

     

    Before you twist those nine strands into rope after completing the initial twists...just cut them free and see what happens to them.  You will soon find that they quickly unwind.   This doesnt create a good large cable because it will always want to unwind from its core...

     

    Yes it saves time, but it doesnt make the best rope.  This will happen on any machine or ropewalk.  It usually starts on the ends that were cut, even with a sharp blade.   The three larger ropes untwist just a little bit......then the individual strands in each of those that were not laid up properly begin to untwist...then it just creeps along the whole length of rope in short order as you handle the ends with your hands.   

     

    Hope that makes sense.  Its much easier to show a person while they are in my shop than explain it in writing.

  4. Yes it did get smaller but its a much better rope.   That will happen.   If it still unravels its because your using multiple lines on each and twisting them first.   Those wont stay twisted because you never twisted them individually first to create tension.  That being said,   it will still hold together well enough.  For example,  when I make a larger cable I first make three smaller cables with tension so they wont unwind.  Then I take those three and make the larger rope.   You end up with an opposite twist however so you have to remember to correct that by creating the first three strand with the opposite twist you will eventually require.

     

    I do understand what Gaetan is saying though.   Standing while twisting is very awkward.  Better if that end is on a table top as is mine.  Then you are able to control the "walking" of that end better.   You will also get a better "feel" for that tension.  I am sure his more complex rope walk works great as well.  But like I said....simple is just as good.   I dont use any weights at all and I simply slide the end on a table and "feel the tension".  I can adjust if needed.

     

     

    It will be difficult to achieve the same results over and over again without that sort of control.  Standing up like that will make it very hard to replicate over and over again.

  5. No

     

    I built the longboat in boxwood and in bass.   The pinnace in Boxwood and now in holly.   Others from my club have built it in pear.  Its just a personal decision based on teh color.  Holly is super easy to work with.  Especially with the planking.  It bends so easily.  I have not finished that version yet.  I was curious what a fully white or "whitish"  model would look like.   Maybe like bone.   So I gave it a shot for fun.

     

    Still have it but unfinished.  Maybe I will offer it up to someone else to finish it.  Dont know if i will ever get around to it.

  6. Good luck and i am eagerly awaiting some progress reports.  Here are the answers to your questions.....

     

    The Basswood sheet that contains the bulkheads is 3/32 of an inch thick. Also on this sheet are the 2 lengths for the keel & 2 rudders. is this just extras or are we intended to glue then together to get a thickness of 3/16? The same occurs on the sheet with the Stem. I have 2 stems.

     

    Just extras...I had the room so why not add them just in case...shhhh dont let Expo know!!!

     

    Next question, On the 3/32 sheet with the stem there are 2 small pieces which I believe are the stern post. Again is the intent to glue them together to get more thickness. Finally there are 3 bow blocks on this sheet. I can figure out what to do with 2 bow blocks but is the 3rd one extra?

     

    All just extras....

     

    A final comment, since Jeff is backed up supplying all of us builders with wood. This log may move a bit slow for the next couple of months. I started it now because this is a great opportunity to gather info from those who have gone before me. I also felt this was the best way to ask questions without cluttering someone else's build.

     

    Note:  Just use some wipe on poly on all the basswood frames which will match the boxwood nicely.   Sand both sides of the board with teh bulkheads with very fine sandpaper to get a smooth finish BEFORE you remove them each from the sheet and to also remove the laser char.   Then give them several coats of wipe on poly.....leave the laser cut edges alone though.....dont sand those too much at all until you have to fair the hull.  Hope that makes sense.

     

    Enjoy the project.
